Miley's Bizarre ...Miley Cyrus took every precaution to ensure that her Disney image got left in the dust. Her performance of "We Can't Stop" started weird and ended even weirder.

Robin Thicke Can...Cyrus ended her performance in a set of nude, plastic underwear.

Taylor Swift Mou...Taylor Swift is known for bashing her exes in her songs, but the notorious good girl is rarely caught cursing. Lucky for us, the camera panned over BFFs Taylor Swift and Selena Gomez just as Taylor’s most-recent ex, Harry Styles of One Direction, took the stage. Swift could clearly be seen mouthing “Shut the f*** up” in Gomez’s ear. —XFINITY Entertainment Staff (Photo by Scott Gries/Invision/AP)The opinions expressed are solely those of the author and do not necessarily reflect the views of Comcast.

'N Sync ReunionIt was the worst kept secret of the VMAs, but awesome nonetheless. Lance Bass, Chris Kirkpatrick, JC Chasez, and Joey Fatone joined Justin Timberlake onstage for a short 'N Sync reunion. Needless to say, it was amazing and had the entire crowd — from Taylor Swift to Rihanna —rocking out. —XFINITY Entertainment Staff (Photo by Rick Diamond/Getty Images)The opinions expressed are solely those of the author and do not necessarily reflect the views of Comcast.

Calm KanyeNo, Kanye didn't interrupt Taylor's acceptance speech this year, but his appearance did surprise. The usually over-the-top rapper’s rendition of “Blood on the Leaves” was shockingly calm. The performance featured a simple silhouette of West singing against a backdrop of trees. —XFINITY Entertainment Staff (Photo by Rick Diamond/Getty Images)The opinions expressed are solely those of the author and do not necessarily reflect the views of Comcast.

No Love for One ...Despite winning the Song of the Summer award by an overwhelming number of votes, One Direction still felt the wrath of an unruly VMA crowd. The guys were a little taken aback by the resounding boos that echoed throughout the Barclay Center when they took the stage to accept their prize. We're guessing Taylor Swift was the ringleader. —XFINITY Entertainment Staff (Photo by Charles Sykes/Invision/AP)The opinions expressed are solely those of the author and do not necessarily reflect the views of Comcast.

Katy Perry's New...Katy Perry closed out the show with her new song "Roar," but it was her grill that left people talking.
